Method Detail

asStage

public static <DATA,RESULT> Stage<DATA> asStage(Inflector<DATA,RESULT> inflector)

Creates a terminal Stage that implements Inflecting interface and returns the provided Inflector instance when the Inflecting.inflector() method is called.

Parameters:

inflector - a request to response transformation to be wrapped in a stage.

Returns:

a stage that wraps the supplied Inflector.

extractInflector

public static <DATA,RESULT> Inflector<DATA,RESULT> extractInflector(java.lang.Object stage)

(Optionally) extracts an inflector from a processing stage, provided the stage implements Inflecting interface. Otherwise method returns null.

Type Parameters:

DATA - data type transformable by the stage and returned inflector.

RESULT - type of result produced by a successful inflector data transformation.

Parameters:

stage - a stage to extract the inflector from.

Returns:

extracted inflector if present, null otherwise.

chain

public static <DATA> Stage.Builder<DATA> chain(com.google.common.base.Function<DATA,DATA> transformation)

Start building a stage chain.

Parameters:

transformation - root transformation function.

Returns:

linear accepting chain builder.

chain

public static <DATA> Stage.Builder<DATA> chain(ChainableStage<DATA> rootStage)

Start building a stage chain.

Parameters:

rootStage - root chainable linear stage.

Returns:

linear accepting chain builder.
